ABSTRACT

In the present scenario, nanotechnology is an important enabling active area of research in modern material sciences. Metal nanoparticles are more effective because of high surface to volume ratio. Among all the metallic nanoparticles silver nanoparticles draw more attention due to its unique physical, chemical and biological properties. Plant and microorganisms are majorly applied for green synthesis of metallic nanoparticles. Among all organisms plants seem to be the best candidates for biosynthesis of silver nanoparticles and they are suitable for large scale biosynthesis. In the present study, Plant extract of Terminalia chebula was used for the synthesis of silver nanoparticles from silver nitrate solution. The formation and stability of the reduced silver nanoparticles in the colloidal solution were monitored by UV-vis spectrophotometer analysis. Antibacterial activity of the silver nanoparticles was performed by agar well diffusion method against wound causing S.aureus. Efficient antibacterial activity of the synthesized silver nanoparticles proves the application potential of green synthesis in the area of nano-medicine.
